This chain of limestone shoals, stretching 48 kilometers between Rameswaram Island in India and Mannar Island in Sri Lanka, has long been a subject of fascination. The ESA image provides stunning detail of the bridge's structure, sparking renewed interest in its geological history and cultural significance. ESA’s image reveals a stark contrast between the deep blue waters of the Indian Ocean and the lighter hues marking the shallow regions around the Ram Setu. Here, the seabed dips to a depth of only 1 to 10 meters, suggesting a submerged landmass slowly revealing its secrets. Exposed sandbanks further bolster this theory. The picture also highlights the bridge's ecological importance. Mannar Island on the Sri Lankan side boasts thriving ecosystems protected within a national park. The island itself is connected to mainland Sri Lanka by modern bridges. <cmsannotation type="cmsannotation" annotationid="Myth and science collide" comment="subhead" text="Myth and science collide">Myth and science collide </cmsannotation>Legends surrounding the Ram Setu claim it was built by Lord Rama, a revered Hindu deity, with the help of his monkey army. However, scientific evidence suggests a more natural origin story. Geologists believe the shoals are remnants of a landmass that once connected the Indian subcontinent to Sri Lanka. Historical records seem to support this theory, indicating that the bridge was indeed a traversable land route until the 15th century, when powerful storms gradually submerged portions of the path. On the Indian side, Rameswaram Island, also known as Pamban Island, beckons with its historic temples and vibrant culture.

Since centuries, India has been building engineering marvels, leaving everyone in awe. Be it hanging pillar in a 16th century temple, or musical pillars, or largest monolith in the world, India has turned out stones and ideas into fascinating objects with chisel and hammer and engineering techniques. 
 
From building temples to services for the mankind, India has numerous engineering marvels to boast of. Indians have linked two lands separated by seas and have connected masses to remotest of the villages with bridges. 
 
You name it, we have already conquered it. Such engineering marvels can be seen in railways. For instance, the Pamban sea bridge, the second longest sea bridge, after Worli Sea Link in Mumbai that was opened to public in 2010. 
 
Pamban Sea Bridge was opened to public in 1914 and was India’s first sea bridge that connected southern Rameswaram town on Pamban Island to Palk Strait. The bridge spans a 2 km-strait between mainland and island and is the only surface transport link between the two. 
 
It is also India’s first Cantilever bridge and there were many challenges while constructing it, such as it was built in world’s second highly corrosive environment, first one being Mexico. 
 
Here are some other interesting details about the bridge:
